The language of physics is mathematics. (return to top) |
|
|
1. Physics relies on standardized units to define properties and relationships among physical quantities. (AKSci - B.1) |
• Use and convert units within an appropriate system of measurement (emphasize the SI system of measurement). |
|
2. Physical phenomena can be analyzed mathematically from fundamental principles. (AKSci - B.1, D.1) |
• Graph relations between displacement vs. time and velocity vs. time. |
|
3. Proportional relationships can be developed between quantities. (AKSci - B.1) |
|
|
Motion in one and two dimensions can be described by analyzing each dimension separately. (return to top) |
• Construct graphs representing one and two-dimensional motion. • Identify and contrast examples of accelerated and constant velocity motion. |
|
Net forces cause masses to change their motion. (return to top) |
|
|
1. Free Body Diagrams specify which forces are involved in specified situations. (AKSci - A.6) |
• Construct a Free Body Diagram of an object in uniform motion and accelerated motion. • Using Newton's Universal Gravitational Law, explain the motion of a satellite around Earth. |
|
2. There are specific relations among force, mass and acceleration. (AKSci - A.6) |
|
|
An object with energy can do work. (return to top) |
|
|
1. Total of energy and the mass can neither be created nor destroyed. (AKSci - A.8b) |
• Calculate the speed of a falling object using Conservation of Mechanical Energy • Identify the flow of energy through a system. |
|
2. Heat is the transfer of thermal energy. (AKSci - A.2, A.9) |
|
|
Moving objects possess momentum. (return to top) |
|
|
1. Total momentum is constant unless impulse is done. (AKSci - A.6) |
• Demonstrate that total momentum remains unchanged in a collision. • Describe the changes in motion when two objects collide. • Describe a collision in which neither energy nor momentum changes. |
|
Waves are generated by objects oscillating in simple harmonic motion. (return to top) |
|
|
1. It is common for energy to be transferred by waves. (AKSci - A.6) |
• Describe how water waves and sound waves are created by oscillating sources. |
|
2. Waves can be categorized by many of their characteristics. (AKSci - A.6) |
• Identify the qualities of a good oscillator. • Calculate the wavelength of a specific tuning fork. |
|
Interactions among particles with electric charge are responsible for the structure of matter. (return to top) |
|
|
1. Electric charge appears in two types: positive and negative, which cannot be created or destroyed. (AKSci - A.1) |
• Determine the magnitude and polarity of electric charge of an object. |
|
2. Interactions between charged particles occur via their respective electric fields. (AKSci - A.1, A.2) |
|
|
• Determine proportional relationships of the current and voltage for simple circuits and compare these values to those measured in actual circuits. |
|
|
Magnetism, like electric charge, is a fundamental property of most matter. (return to top) |
|
|
1. Magnetic charge appears in two types, or poles: north and south. (AKSci - A.1) |
• Compare the effect on a moving electric charge of a magnetic and electric field. • Experiment with the magnetic fields of various magnets. |
|
Electric and magnetic fields and light are related. (AKSci - A.2) (return to top) |
|
|
• Calculate the wavelength of electromagnetic radiation produced by an electron moving in a circle. |
|
|
When light's speed changes, light's direction may change. (AKSci - A.3) (return to top) |
|
|
• Create ray diagrams for an image created by a lens and mirror. |
|
|
Special Relativity relates mass and space. (AKSci - A.16) (return to top) |
|
|
• Explain time, mass and contraction of space with respect to special relativity. |
